IMPROVEMENT IN MOLE-PLQWS.

Specification forming part of Letters Patent No. 176,201, dated April 18,1876; application filed February 14, 1876.

To all 'whom it may concern:

Beit known that I, JOHN SCOTT, of Morgan county and State of Illinois, have invented an Improved Dtching Machine Mole for Laying Drain-Tiles, of which the following is afull, clear, and exact description, reference being had to the accompanying drawing, and the letters of reference marked thereon, making a part of this specification, in which- Figure 1 is a top-plan view. Fig. 2 is a longitudinal sectional view. Fig. 3 is a section on the line .r Fig. 2.

The nature of my invention consists in forming the solid mole, the bottom thereof being flat, and also having a vertical slotted bearing for the reception of the colter or cutting-beam, with a hollow chamber at its rear to receive the end of the tile, all arranged as more fully hereinafter described.

The construction and operation of my invention are as follows A is the mole, and is made of cast or wrought iron, or of any suitable material. The mole A is hat at its under surface, as shown at A', Figs. 2 and 3, which causes it not only to run more smoothly, but also to leave a flat bed for the drain-tiles. The top and sides of the mole are curved or convex, and from its center toward its forward section it is of a gradually-contracting conical form, terminating in a sharp-pointed toe, a.' This mole is also cast with a hollow or socket bearing, B, at its head, a suitable form or contour for which is shown in Fig. 2, and also with a vertical bearing-opening, B', in which the lower end of the colter or cutting-beam, which is designed to make the incision in the soil, and which attaches the mole to the plowbeam, enters and has its bearing. At the center of the head of the solid section of the mole, and within the hollow section B, is secured a clevis or hook, U, to which is attached a chain, C', which is designed to draw and properly lay in the drain, and immediately after the mole, a series or succession of drain-tiles, D D, constructed of any snitable material, and which are strung and held on the chain by means of a cap, E, and key E'. The cap is constructed of any suitable material, and is formed with a center opening, the diameter of which being just suflicient to permit of its passing .freely over the links of the chain. l

The operation is as follows: The molebeing attached to the beam of a plow or a like bearing on a ditching-machine by means of a oolter or bar entering and being secured in the slotted opening B', and the chain O' being now attached to the clevis or hook C, the drain-tiles D D are strung on the same, and the cap E is then Vpassed ou and pushed against the opening at the rear of the last of the succession, and fastened by means of a key, E', which is inserted through the link of the chain, which is immediately behind the cap E. By reference to Figs. l and 2, more especially the latter, it will be seen how entirely the annular wall of the socket protects the forward open end of the first of the series of drain-tiles. The several features being thus arranged and connected, at the point where the drain is desired a sloping or angular excavation is made, to allow all of the chain and tiles to pass. Owing to the form of the mole, the draft required is comparatively slight, and the drain, owing to the fact that the earth is, as it were, gradually pressed, is much more perfect and smooth, leaving an arched wall of the most compact form, the dat section of the mole forming the bed of the ditch, and its sides or top the wall or arch, and owing to the fact that the rear section of the mole is much larger in diameter than thedrain-tiles, they are easily drawn along to their desired position, and their interior passage being protected from all danger of being obstructed by falling clods or loose earth, when the pipes have been carried after the mole to the point whereit is designed to deposit the same, the key being removed, the chain readily draws out, leaving the tiles in the desired position.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The solid mole A, having a flat bottom,

A', and a hollow Vchamber or bearing, B, at its rear, provided with a clevis or hook at its center and a vertical slotted bearing, B', the

whole constructed and arranged to operat substantially as described.

2. The mole A, having socket-bearing B and clevis or hook C, in combination with chain G', cap E, and key E', the Whole constructed and arranged to permit of the tiles being laid, substantially as described.

In testimony whereof I have signed my name to this specication in the presence ot' two subscribing witnesses.

JOHN SCOTT.
